  • Patent number: 10175286
    Abstract: The Power Line Fault Locating System is a means of locating faults in a utility power system by sampling the noise at multiple positions around the system and correlating and summing the resulting data. When the processed data produces a spike, a noise source has been detected. The position of the spike in the data will indicate the location of the noise source with great precision. With three of more receivers the location of the fault can be determined in two dimensions. The invention can operate on both continuous noise resulting from minor flaws in the power system as well as the noise burst resulting from a power system failure. Noise resulting from minor flaws may come from slack line fittings, electrical leakage in insulators or at poles. A burst of noise may come from insulator flash over, lightning strike, or something contacting a power line.

    Abstract: A circuit, a system and/or a method detect a passive electrical connection and/or an active electrical connection between an electrical device and a power supply. An integrity of the electrical connection between the electrical device and the power supply is monitored to determine if the electrical device may have access to power and/or to determine if the electrical device may be secure while on display. A high frequency AC signal is modulated onto a positive power rail between the electrical device and the power supply. Capacitance circuitry of the electrical device may remove the high frequency signal from the positive power rail. An absence of the high frequency signal on the positive power rail indicates that the electrical connection exists between the electrical device and the power supply. A presence of the high frequency signal on the positive power rail indicates that the electrical connection does not exist between the electrical device and the power supply.

  • Publication number: 20140062708
    Abstract: A voltage gradient detector provides notice when a potentially hazardous voltage gradient is present in water, employing at least one pair of spaced-apart electrodes connected to an LED. The electrode spacing is selected such that, when exposed to a sufficiently large voltage gradient, the voltage between the electrodes causes activation of the LED. The LED can provide visual illumination, or can be a part of a switching device such as a photoMOS relay that in turn activates an alarm device such as an audible sounder or a high-intensity light. Sensitivity in multiple directions can be attained by employing a pair of LEDs between the electrodes, and by employing three pairs of electrodes and associated LED pairs, with the pairs of electrodes being spaced apart along substantially orthogonal axes. These pairs may be discrete or may share an electrode in common.

  • Patent number: 8599030
    Abstract: A communication apparatus includes a communication connector, a communication section, a connection section, a state detector, a controller and a warning section. The communication section controls communication performed through the communication connector, to which a communication plug is connected. The connection section connects the communication connector and the communication section. The state detector generates a state detection signal corresponding to a connection state of the communication plug relative to the communication connector. The controller determines which of a normal connection state, an improper connection state and a non-connection state the communication plug is in based on the state detection signal. The controller also controls an ON-OFF operation of the connection section. The warning section notifies a user of results determined by the controller.

  • Patent number: 8599031
    Abstract: A system for detecting stray voltage in a conductive object is disclosed herein. The system includes a pick-up element, electrical circuitry, a housing for enclosing the circuitry, a support for mounting the housing, and an indicator. The pick-up element is separated from the conductive object and capable of detecting an electric field from the conductive object. The support of the housing is such that the pick-up element remains separated from the conductive object. The electrical circuitry determines a voltage level corresponding to the electric field detected by the pick-up element and generates, based on a comparison of the determined voltage level relative to a reference voltage level, an indicator signal representative of whether stray voltage is present in the conductive object. Based on the indicator signal, the indicator indicates to a user of the system whether stray voltage is present in the conductive object.

  • Patent number: 8537022
    Abstract: The invention provides a method for configurable ground monitoring of a workbench, and the method comprises the steps as follows. The step of detecting if each of monitored objects of a monitor device is enable should be performed first. A digital value of each of the monitored objects according to detecting result is then calculated and accumulated. The step of detecting if each of the monitored objects reaches a predetermined number of samples is performed, and the step of calculating an average value of each of the monitored objects according to detecting result is followed. The average measured value is compared with a predetermined digital limit-value of each of the monitored objects; furthermore, a corresponding alarm will be sounded when the average measured value exceeds the predetermined digital limit-value. The digital value and a compared result are then sent, and then the step of detecting if the operator ground connection is enabled is performed.
